The inductive displacement sensors in the SM34 series from a.b.Jödden have a diameter of just 10 mm and detect displacements of 5, 10, 15 or 20 mm. Their integrated electronics evaluate the change in inductance caused by the axial displacement of a NiFe metal core. Operating voltages of 5, 12 or 24 V(DC) and a low operating current also enable use in mobile systems. The displacement-proportional, analog output signal of 0 to 10, 0 to 5 or 0 to 4 V(DC) can be processed directly by many evaluation units. The version with a current output of 4 to 20 mA is available in 2-wire technology. Thanks to protection class IP67, the sensors can withstand extreme environmental conditions such as oil mist, mud, rain and dust, they can withstand shock loads of up to 250 g SRS and vibration loads of up to 20 g rms.
